Description

[CROSS REFERENCE TO RELATED APPLICATIONS]
The present invention is based on and claims priority to the PCT international application having application number PCT/CN2020/075431 and filing date February 14, 2020, and the PCT international application having application number PCT/CN2020/079061 and filing date March 12, 2020, the entire contents of which are incorporated herein by reference.
The present invention relates to the field of communications, and in particular to an information processing method, apparatus, storage medium, processor, and electronic device.

Currently, in the related art, in the process of determining a Hybrid Automatic Repeat reQuest (HARQ) process number in a New Radio (NR) Uu system, a base station can assign a quasi-static scheduling (SPS) downlink transmission resource to a terminal. When configuring downlink SPS transmission resources, the base station may configure multiple HARQ process numbers for each set of SPS transmission resources. In addition, in the NR system, the base station can further assign an uplink configured grant (UL CG) to the terminal. When configuring UL CG resources, the base station may configure multiple HARQ process numbers for each set of UL CG resources.

As can be seen, the related art only provides a method for determining the HARQ process number when the base station configures downlink SPS transmission resources or UL CG resources, but does not mention a method for determining the HARQ process number for a sidelink (SL) configuration grant (abbreviated as Configured Grant, CG).

Currently, no effective solutions have been proposed to address the above issues.

In order to allow those skilled in the art to better understand the proposal of the present invention, the following clearly and completely describes the technical proposal in the embodiment of the present invention with reference to the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, and not all of the embodiments. All other embodiments that a person skilled in the art can obtain without creative effort based on the embodiment of the present invention should fall within the protection scope of the present invention.

In addition, the terms "first", "second", etc. in the present specification, claims, and drawings are intended to distinguish between similar objects and are not necessarily intended to describe a particular order or sequence. As will be understood, the data used in this manner can be interchanged where appropriate, whereby the embodiments of the present invention described herein can be performed in an order other than that shown or described herein. In addition, the terms "comprise", "have", and any variations thereof are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or apparatus of a series of steps or units explicitly recited, but may include other steps or units not explicitly recited or inherent to these processes, methods, products, or apparatus.

Figure 1 is a schematic diagram of a D2D transmission technology according to the related art. As shown in Figure 1, device-to-device (abbreviated as D2D) communication is a transmission technology based on sidelink (abbreviated as SL), which is different from the method in which communication data is transmitted and received via a base station in a conventional cellular system. The D2D system adopts a method of direct communication from terminal to terminal, so it has higher spectral efficiency and lower transmission delay. The vehicle-to-thing communication system is based on D2D transmission technology, and the 3rd Generation Partnership Project (3GPP) has defined two transmission modes, mode A and mode B.

In mode A, the terminal's transmission resources are assigned by the base station. The terminal transmits data in the sidelink based on the resources assigned by the base station. The base station can assign resources for one-time transmission to the terminal, and can also assign resources for quasi-static transmission to the terminal. In mode B, the terminal selects one resource from the resource pool to transmit data.

Between NR-vehicles and other devices (abbreviated as Vehicle to Everything, V2X) autonomous driving needs to be supported, which places higher requirements on data interaction between vehicles, such as higher throughput, lower latency, higher reliability, greater coverage, and more flexible resource allocation. NR-V2X introduces unicast and multicast transmission methods. In addition, Long Term Evolution (abbreviated as LTE)-V2X also supports broadcast transmission methods.

In the case of the unicast transmission method, unicast transmission is performed between a transmitting terminal and a receiving terminal. FIG. 2 is a schematic diagram of a unicast transmission method according to the related art. As shown in FIG. 2, UE1 is a transmitting terminal and UE2 is a receiving terminal, so that unicast transmission can be performed between UE1 and UE2.

In the case of a multicast transmission method, the receiving terminals include all terminals in one communication group or all terminals within a specified transmission distance. Figure 3 is a schematic diagram of a multicast transmission method according to related technology. As shown in Figure 3, UE1, UE2, UE3, and UE4 constitute one communication group, UE1 is the data sender, and the other terminal devices UE2, UE3, and UE4 in the group are all receiving terminals.

In the case of a broadcast transmission method, the receiving terminal can be any one terminal. FIG. 4 is a schematic diagram of a broadcast transmission method according to the related art. As shown in FIG. 4, when UE1 is a transmitting terminal, other terminals UE2, UE3, and UE4 around UE1 can all be set as receiving terminals.

Note that NR-V2X also introduces several types of transmission modes, namely, mode 1 and mode 2. In mode 1, the network allocates transmission resources to the terminal (i.e., mode A above), and in mode 2, the terminal selects the transmission resources (i.e., mode B above). In order to improve the reliability of data transmission, a feedback channel is introduced in the sidelink. Figure 5 is a schematic diagram of a data transmission process in NR-V2X according to the related art. As shown in Figure 5, UE1 and UE2 constitute one unicast link. UE1 transmits sidelink data to UE2. UE2 transmits sidelink feedback information, i.e., HARQ ACK or NACK, to UE1 based on the detection result of the received sidelink data. After receiving the feedback information from UE2, UE1 determines whether to retransmit the data to UE2. Note that UE1 may further determine whether the receiving terminal UE2 needs to transmit feedback information. For example, in the case of broadcast communication, feedback by the receiving side is not required, but in the case of unicast communication, feedback by the receiving side is required to improve system reliability. Specifically, UE1 includes indication information in the sidelink control information (SCI), thereby indicating to the receiving terminal whether or not sidelink feedback is required.

NR-V2X further supports resource allocation methods of mode 1 and mode 2. In mode 2, the terminal independently selects transmission resources from a resource pool to perform sidelink transmission, i.e., the above-mentioned mode B. In mode 1, the network side device allocates sidelink configuration grant transmission resources to the terminal, i.e., the above-mentioned mode A. Specifically, the network side device may allocate sidelink configuration grant transmission resources to the terminal through a dynamic scheduling method, or may allocate SL CG transmission resources to the terminal. The CG resource allocation method mainly includes two types of configuration grant methods, namely, a first type of configuration grant (type-1 configured grant) and a second type of configuration grant (type-2 configured grant).

The first type of configuration grant refers to a network device configuring a sidelink configuration grant transmission resource to a terminal through Radio Resource Control (RRC) signaling. The RRC signaling configures all transmission resources and transmission parameters, including time domain resources, frequency domain resources, demodulation reference signals (DMRS), and modulation and coding schemes (MCS). The UE then performs sidelink transmission in the configured time-frequency resources using the configured transmission parameters.

The second type of configuration grant adopts a two-step resource configuration method, that is, RRC + Downlink Control Information (DCI) method. First, transmission resources and transmission parameters, including the period of time-frequency resources, the number of HARQ processes, etc., are configured by RRC signaling, and then the transmission of the second type of configuration grant is activated by DCI, and at the same time, other transmission resources and transmission parameters, including time domain resources, frequency domain resources, MCS, etc., are configured. After receiving RRC signaling, the UE cannot immediately perform sidelink transmission using the resources and parameters configured by the higher layer parameters, but can perform sidelink transmission only after receiving the corresponding DCI activation and other resources and transmission parameters are configured. In addition, the network side device can deactivate the transmission of the configuration through DCI, and the terminal cannot perform sidelink transmission using the transmission resources after receiving the deactivation DCI.

If the network side device has already allocated the transmission resources of the configuration grant to the terminal, when the terminal has sidelink data waiting to be transmitted, the terminal does not need to send a scheduling request (SR) or a buffer status report (BSR) to the network side device to request transmission resources, and can directly use the transmission resources to perform transmission, thereby reducing the transmission delay. In the sidelink configuration grant, the network side device may allocate periodic transmission resources, and in each period, the network side device may configure multiple transmission resources. Figure 6 is a schematic diagram of a network side device configuring transmission resources according to the related art. As shown in Figure 6, the transmission resources of the configuration grant by the network side device are periodically repeated transmission resources, and each period includes four sidelink configuration grant transmission resources.

In the resource allocation method of mode 1, when sidelink feedback is in an active state, the receiving terminal sends feedback information to the transmitting terminal based on the sidelink data reception status. The transmitting terminal reports the sidelink feedback information (SL HARQ-ACK) to the network side device. The network side device then determines whether retransmission resources need to be allocated based on the SL HARQ-ACK reported by the transmitting terminal.

In the sidelink configuration grant transmission, the network side device can configure the transmission resource of the sidelink configuration grant to the terminal and allocate the transmission resource of the physical uplink control channel (abbreviated as PUCCH). The terminal can report the sidelink feedback information to the network side device in the PUCCH. When the network side device receives the NACK feedback information reported by the terminal, it needs to allocate the retransmission resource by dynamic scheduling and indicate the HARQ process number in the DCI of the dynamic scheduling, thereby indicating the HARQ process to which the retransmission resource to be allocated to the terminal belongs. Therefore, the network side device needs to determine the HARQ process number corresponding to the sidelink transmission.

According to one embodiment of the present invention, an embodiment of a method for processing information is provided. It is to be noted that the steps illustrated in the flowcharts of the drawings may be performed, for example, in a computer system as a set of computer-executable instructions, and that although a logical order is shown in the flowcharts, in some cases the steps shown or described herein may be performed in an order different from that shown here.

In this embodiment, an information processing method executed in the terminal device is provided. FIG. 7 is a flowchart of an information processing method according to one embodiment of the present invention. As shown in FIG. 7, the method includes the following steps S70 to S72.

In step S70, configuration information is received from the network side device, and the configuration information is used to configure a sidelink configuration grant transmission resource, where the sidelink configuration grant transmission resource is a transmission resource located in a resource pool.

In step S71, time domain information corresponding to the sidelink configuration grant transmission resource is determined based on the configuration information.

In step S72, a first hybrid automatic repeat request process number is determined based on the time domain information corresponding to the sidelink configuration grant transmission resource.

According to the above steps, a method can be adopted in which configuration information is received from a network side device, the configuration information is used to configure a sidelink configuration grant transmission resource, and the sidelink configuration grant transmission resource is a transmission resource located in a resource pool. Time domain information corresponding to the sidelink configuration grant transmission resource is determined according to the configuration information, and a first hybrid automatic repeat request process number is determined according to the time domain information corresponding to the sidelink configuration grant transmission resource. Thus, the objective of providing a HARQ process number determination method for a sidelink configuration grant is achieved, the technical gap of being unable to determine a HARQ process number in terms of a sidelink configuration grant is effectively filled, the technical effect of the flexibility and diversity of the HARQ process number determination method is enhanced, and the technical problem of the lack of a determination method for a HARQ process number for a sidelink configuration grant in related technologies is resolved.

In the above configuration information, a sidelink configuration grant transmission resource may be configured, and a PUCCH transmission resource may be configured. The PUCCH transmission resource is a PUCCH resource corresponding to the sidelink configuration grant transmission resource, that is, the sidelink feedback information associated with the sidelink data transmitted in the sidelink configuration grant transmission resource is reported to the network side device by the PUCCH transmission resource. For the terminal device, the first hybrid automatic repeat request process number can be determined based on the time domain position of the sidelink configuration grant transmission resource.

One DFN period includes 10240 subframes, and the period of the synchronization signal is 160 ms. Assuming that one synchronization period includes two synchronization subframes, there are 128 synchronization subframes in one DFN period, and the length of the bitmap for indicating the time domain resources of the resource pool is 10 bits. Therefore, two reserved subframes are required, and the number of remaining subframes is (10240-128-2=10110), which is divisible by the 10 bits of the bitmap length, so that the remaining subframes are renumbered 0, 1, 2, ..., 10109, and the first 3 bits of the bitmap are 1 and the remaining 7 bits are 0. That is, in the remaining subframes, the first 3 subframes of each of the 10 subframes belong to the resource pool, and the remaining subframes do not belong to the resource pool. To indicate whether all subframes belong to the resource pool, the bitmap needs to be repeated 1011 times in the remaining subframes, and since there are three subframes in each bitmap period, a total of 3033 subframes belong to the resource pool in one DFN period. Each time slot index in the resource pool corresponds to one time slot index in the DFN period. For example, time slots 0, 1, 2, 3, 4, and 5 in the resource pool correspond to time slots 0, 2, 4, 13, 14, and 15 in the DFN period. When the network configures a sidelink configuration grant transmission resource, it is associated with one resource pool, and the sidelink configuration grant transmission resource configured by the network is a transmission resource located in the one resource pool.

In this embodiment, the time domain information corresponding to the sidelink configuration grant transmission resource is the time slot index of the sidelink configuration grant transmission resource in the resource pool. For example, in the above embodiment, the resource pool in which the sidelink configuration grant transmission resource is located includes 3033 subframes, so the time domain information corresponding to the sidelink configuration grant transmission resource is the time slot index in the resource pool, i.e., the time slot index in the range [0, 3032].

Optionally, the time domain information corresponding to the sidelink configuration grant transmission resource is a timeslot index in the timeslots that can be used for the resource pool. For example, for the above embodiment, the timeslot set that can be used for the resource pool is the remaining subframes, and the corresponding timeslot index range is [0, 10109].

As an option, depending on the above setting information,
(1) A periodicity of a sidelink configuration grant transmission resource;
(2) the total number of HARQ process numbers corresponding to the currently configured grants;
(3) an HARQ process number offset used to determine the first HARQ process number corresponding to the currently configured grant;
(4) a time slot corresponding to a time domain resource of the sidelink configuration grant transmission resource.

In one embodiment, the configuration information includes a timeslot offset indication and a periodicity parameter, and a sidelink configuration grant transmission resource is determined based on the timeslot offset indication and the periodicity parameter. The timeslot offset indication is used for determining time domain information of a first sidelink configuration grant transmission resource within one system frame number period (or directly within a frame number period). The timeslot offset indication is expressed as a number of timeslots, the number of timeslots representing a number of physical timeslots or a number of logical timeslots, where a logical timeslot is a timeslot in a resource pool associated with the sidelink configuration grant transmission resource or a timeslot available for the resource pool. The periodicity parameter is used for determining a period of the sidelink configuration grant transmission resource, the number of timeslots representing a number of physical timeslots or a number of logical timeslots, where a logical timeslot is a timeslot in a resource pool associated with the sidelink configuration grant transmission resource or a timeslot available for the resource pool.

Optionally, step S72 of determining the first hybrid automatic repeat request process number based on time domain information corresponding to the sidelink configuration grant transmission resource may comprise the following execution steps S720 and S722:

In step S720, a periodicity parameter is determined based on the configuration information, and the periodicity parameter is the period of the sidelink configuration grant transmission resource.

In step S722, a first hybrid automatic repeat request process number is determined based on the time domain information and periodicity parameters corresponding to the sidelink configuration grant transmission resource.

As an alternative, the period of the sidelink configuration grant transmission resource is expressed in terms of the number of time slots, which is used to describe the number of time slots in the resource pool in which the sidelink configuration grant transmission resource is located. Or, as an alternative, the period of the sidelink configuration grant transmission resource is expressed in terms of the number of time slots, which is used to describe the number of candidate time slots for the resource pool.

As an option, the period of the sidelink configuration grant transmission resources is expressed in number of logical time slots and also in number of physical time slots.

When the parameter periodicity is expressed as the number of time slots, the corresponding first HARQ process number is determined based on the time domain position of the sidelink configuration grant transmission resource in the resource pool in which the sidelink configuration grant is located, using the formula HARQ Process ID = [floor (CURRENT_slot / periodicity)] mod nrofHARQ-Processes + harq-procID-offset. The meaning of each parameter in the formula is as follows:

(1) CURRENT_slot represents a timeslot corresponding to the time domain resource of the sidelink configuration grant transmission resource, and the index of the timeslot is the timeslot index in the resource pool in which the sidelink configuration grant is located. The value range of this parameter is [0, N-1], where N represents the total number of timeslots contained in the current resource pool, and the index of the timeslot is the timeslot index in the resource pool in which the sidelink configuration grant is located.

(2) periodicity represents the period of the sidelink configuration grant transmission resource and is expressed in time slots. It also represents the number of time slots in the resource pool in which the sidelink configuration grant is located.

(3) nrofHARQ-Processes represents the total number of HARQ process numbers corresponding to the sidelink configuration grant.

(4) harq-procID-offset is used to determine the first HARQ process number corresponding to the sidelink configuration grant. Optionally, if the network side device does not configure this parameter, the value of this parameter is 0.

In the above formula, mod represents the modulo operation and floor represents the truncation operation.

As shown in FIG. 8 again, the network side device configures the transmission resources of the sidelink configuration grant in a resource pool. The three time slots of the period of the sidelink configuration grant represent the three time slots in the resource pool. The first time slot position of the sidelink configuration grant is time slot 2, and according to the period of the sidelink configuration grant, time slots such as time slot 5, time slot 8, time slot 11, etc. include the transmission resources of the sidelink configuration grant.

In the above formula for calculating the HARQ process number, CURRENT_slot represents the time slot in which the transmission resource of the sidelink configuration grant is located in the resource pool, i.e., time slot 2, time slot 5, time slot 8, time slot 11, time slot 14, time slot 17...time slot 3032, etc. Periodicity represents the period of the transmission resource of the sidelink configuration grant, which can be expressed as the number of time slots in the resource pool in which the sidelink configuration grant is located, i.e., the period is three time slots. If the parameters are set such that nrofHARQ-Processes = 4 and harq-procID-offset = 0, the HARQ process numbers corresponding to the sidelink configuration grant are 0, 1, 2, and 3, respectively. In this embodiment, the HARQ process numbers corresponding to the transmission resources in the time domain positions of the sidelink configuration grant, such as time slot 2, time slot 5, time slot 8, time slot 11, time slot 14, and time slot 17, are 0, 1, 2, 3, 0, 1, etc., respectively.

In the process of determining the first hybrid automatic repeat request process number based on the time domain information corresponding to the sidelink configuration grant transmission resource, the network side device configures the sidelink configuration grant transmission resource in the terminal, and further determines the corresponding first HARQ process number based on the time domain location of the sidelink configuration grant transmission resource in the sidelink according to the formula: HARQ Process ID = [floor (CURRENT_slot × 10 / (numberOfSlotsPerFrame × periodicity))] mod nrofHARQ-Processes + harq-procID-offset. The meaning of each parameter in the formula is as follows:

(1) numberOfSlotsPerFrame represents the number of time slots contained in each radio frame (Frame or Radio Frame).

(2) periodicity represents the period of the sidelink configuration grant transmission resource and is expressed in milliseconds (ms).

(3) nrofHARQ-Processes represents the total number of HARQ process numbers corresponding to the current sidelink configuration grant.

(4) harq-procID-offset is used to determine the first HARQ process number corresponding to the current sidelink configuration grant. In one alternative embodiment, if the network side device does not configure this parameter, the value of this parameter is 0.

CURRENT_slot represents the time slot corresponding to the time domain resource of the sidelink configuration grant transmission resource, the value range of this parameter is [0, N-1], N represents the total number of time slots contained in the current resource pool, and the index of this time slot is the time slot index in the resource pool in which the sidelink configuration grant is located.

In one possible embodiment, CURRENT_slot = [(DFN x numberOfSlotsPerFrame) + slot number in the frame]. The slot number in the frame represents the index of the sidelink configuration grant transmission resource in one radio frame, and its value ranges from [0, M-1]. M represents the total number of time slots contained in one radio frame. DFN represents the Direct Frame Number. numberOfSlotsPerFrame represents the number of time slots contained in each radio frame (Frame or Radio Frame) and is determined by the subcarrier spacing of the sidelink carrier in which the sidelink transmission is located, or is determined by the uplink subcarrier spacing.

In one possible embodiment, CURRENT_slot = [(SFN x numberOfSlotsPerFrame) + slot number in the frame]. The slot number in the frame represents the index of the sidelink configuration grant transmission resource in one radio frame, and its value ranges from [0, M-1]. M represents the total number of time slots contained in one radio frame. SFN represents the System Frame Number. numberOfSlotsPerFrame represents the number of time slots contained in each radio frame (Frame or Radio Frame) and is determined by the subcarrier spacing of the sidelink carrier in which the sidelink transmission is located, or is determined by the uplink subcarrier spacing.

In the above formula, mod represents the modulo operation and floor represents the truncation operation.

Optionally, the method may further include the following execution step S73:

In step S73, a first sidelink data is transmitted in the sidelink configuration grant transmission resource , where the first sidelink data corresponds to a first hybrid automatic repeat request process number.

The HARQ process number corresponding to the sidelink configuration grant transmission resource determined by the terminal device according to the above method is the first HARQ process number. The terminal device may transmit first sidelink data using the first HARQ process number. The first sidelink data may include PSCCH and PSSCH. In addition, the terminal device may further include the first HARQ process number in sidelink control information (abbreviated as SCI), that is, the sidelink data transmitted in the PSSCH corresponds to the first HARQ process number.

Optionally, the method may further include the following steps S74 and S75:

In step S74, downlink control information is received from the network side device, the downlink control information is used to schedule sidelink transmission resources, and the downlink control information includes a first hybrid automatic repeat request process number.

In step S75, the first sidelink data is retransmitted in the sidelink transmission resource scheduled in the downlink control information.

In transmitting the sidelink configuration grant, the network side device may configure a PUCCH transmission resource for the terminal device. The terminal may report sidelink feedback information to the network side device in the PUCCH transmission resource.

Optionally, the network side device configures one PUCCH transmission resource in each sidelink configuration grant period. In one sidelink configuration grant period, the terminal transmits the first sidelink data to the receiving terminal through the sidelink configuration grant transmission resource, which corresponds to the first HARQ process number. If the sidelink feedback information transmitted by the receiving terminal is a NACK, the terminal reports a NACK to the network through the PUCCH in the period. When the network side device receives the NACK feedback information reported by the terminal, it dynamically allocates a retransmission resource for the sidelink transmission through the DCI and indicates the first HARQ process number in the DCI, so that the terminal device can retransmit the first sidelink data in the sidelink transmission resource scheduled by the downlink control information.

Optionally, the method may further include the following execution step S76:

In step S76, second sidelink data is transmitted in the sidelink configuration grant transmission resource based on the mapping relationship between the first hybrid automatic repeat request process number and the second hybrid automatic repeat request process number, and the second sidelink data corresponds to the second hybrid automatic repeat request process number.

When the terminal transmits sidelink data using a sidelink configuration grant transmission resource, the terminal determines a first HARQ process number based on time domain information of the sidelink configuration grant transmission resource. Furthermore, the terminal may pre-determine a mapping relationship between the first HARQ process number and the second HARQ process number. The terminal device may transmit second sidelink data in the sidelink configuration grant transmission resource using the second HARQ process number based on the mapping relationship. The second sidelink data may include PSCCH and PSSCH. In addition, the terminal device may further include the second HARQ process number in the SCI, i.e., the sidelink data transmitted in the PSSCH corresponds to the second HARQ process number.

Optionally, the method may further include the following steps S77 and S78:

In step S77, downlink control information is received from the network side device, the downlink control information is used to schedule sidelink transmission resources, and the downlink control information includes a first hybrid automatic repeat request process number.

In step S78, the second sidelink data is retransmitted in the sidelink transmission resource scheduled in the downlink control information.

The process number corresponding to the transmission resource of the sidelink configuration grant determined by the network side device according to the PUCCH transmission resource is the first HARQ process number. When the network side device receives a NACK, it dynamically allocates a retransmission resource to the sidelink transmission by DCI, and indicates the first HARQ process number in the DCI. After receiving the DCI and obtaining the first HARQ process number from the DCI, the terminal device may determine that the retransmission resource is a retransmission scheduling for the sidelink transmission of the second HARQ process number based on the mapping relationship between the first HARQ process number and the second HARQ process number.

As can be seen, the first HARQ process number determined by the terminal device based on the time domain information of the sidelink configuration grant transmission resource may be different from the second HARQ process number used when transmitting data on the sidelink configuration grant transmission resource, and the terminal device can further determine the mapping relationship between the first HARQ process number and the second HARQ process number, so that the terminal device can more flexibly or autonomously determine the HARQ process number for sidelink transmission.

This embodiment further provides another information processing method executed in the network side device. FIG. 9 is a flowchart of another information processing method according to one embodiment of the present invention. As shown in FIG. 9, the method includes the following steps S90 to S92.

In step S90, first configuration information is determined, and the first configuration information is used to configure a sidelink configuration grant transmission resource, where the sidelink configuration grant transmission resource is a transmission resource located in a resource pool.

In step S91, time domain information corresponding to the sidelink configuration grant transmission resource is determined based on the first configuration information.

In step S92, a first hybrid automatic repeat request process number is determined based on the time domain information corresponding to the sidelink configuration grant transmission resource.

According to the above steps, a method is adopted in which first configuration information is determined and sent to a terminal, the first configuration information is used to configure a sidelink configuration grant transmission resource, and the sidelink configuration grant transmission resource is a transmission resource located in a resource pool. Time domain information corresponding to the sidelink configuration grant transmission resource is determined according to the first configuration information, and a first hybrid automatic repeat request process number is determined according to the time domain information corresponding to the sidelink configuration grant transmission resource. Thus, the objective of providing a HARQ process number determination method for a sidelink configuration grant is achieved, the technical gap of being unable to determine a HARQ process number in the aspect of a sidelink configuration grant is effectively filled, the technical effect of the flexibility and diversity of the HARQ process number determination method is enhanced, and the technical problem of the lack of a determination method for a HARQ process number for a sidelink configuration grant in related technologies is resolved.

In the first setting information, a sidelink configuration grant transmission resource may be set, and a PUCCH transmission resource may be set. The transmission resource of the sidelink configuration grant set by the network side device to the terminal device is periodic, and each period includes a maximum of N_max (N_max=2 or 3) sidelink configuration grant transmission resources, and one PUCCH transmission resource is set in each period. The terminal device transmits sidelink data using the sidelink configuration grant transmission resource in the period, and reports sidelink feedback information to the network side device using the PUCCH transmission resource. The network side device then determines whether a retransmission resource needs to be assigned to the terminal based on the sidelink feedback information.

For the network side device, first, it can determine a PUCCH transmission resource based on the configuration information; second, it receives a PUCCH in the PUCCH transmission resource, and based on the PUCCH, it determines an SL CG period corresponding to the PUCCH (i.e., the period of the sidelink configuration grant to which the PUCCH belongs) and a sidelink configuration grant transmission resource in the period; and then it determines a first HARQ process number based on the time domain information of the sidelink configuration grant transmission resource.

One DFN period includes 10240 subframes, and the period of the synchronization signal is 160 ms. Assuming that one synchronization period includes two synchronization subframes, there are 128 synchronization subframes in one DFN period, and the length of the bitmap for indicating the time domain resources of the resource pool is 10 bits. Therefore, two reserved subframes are required, and the number of remaining subframes is (10240-128-2=10110), which is divisible by the 10 bits of the bitmap length, so that the remaining subframes are renumbered 0, 1, 2, ..., 10109, and the first 3 bits of the bitmap are 1 and the remaining 7 bits are 0. That is, in the remaining subframes, the first 3 subframes of each of the 10 subframes belong to the resource pool, and the remaining subframes do not belong to the resource pool. To indicate whether all subframes belong to the resource pool, the bitmap needs to be repeated 1011 times in the remaining subframes, and since there are three subframes in each bitmap period, a total of 3033 subframes belong to the resource pool in one DFN period. Each time slot index in the resource pool corresponds to one time slot index in the DFN period. For example, time slots 0, 1, 2, 3, 4, and 5 in the resource pool correspond to time slots 0, 2, 4, 13, 14, and 15 in the DFN period. When the network configures a sidelink configuration grant transmission resource, it is associated with one resource pool, and the sidelink configuration grant transmission resource configured by the network is a transmission resource located in the one resource pool.

In this embodiment, the time domain information corresponding to the sidelink configuration grant transmission resource is a time slot index of the sidelink configuration grant transmission resource in a resource pool. For example, in the above embodiment, the resource pool in which the sidelink configuration grant transmission resource is located includes 3033 subframes, so the time domain information corresponding to the sidelink configuration grant transmission resource is a time slot index in the resource pool, i.e., a time slot index in the range [0, 3032].

Optionally, the time domain information corresponding to the sidelink configuration grant transmission resource is a timeslot index in the timeslots that can be used for the resource pool. For example, for the above embodiment, the timeslot set that can be used for the resource pool is the remaining subframes, and the corresponding timeslot index range is [0, 10109].

Optionally, the method may further include the following execution step S93:

In step S93, first configuration information is transmitted to the terminal, and the first configuration information is further used by the terminal to determine time domain information corresponding to the sidelink configuration grant transmission resource, and to determine a first hybrid automatic repeat request process number based on the time domain information corresponding to the sidelink configuration grant transmission resource.

The first hybrid automatic repeat request process number can be determined not only by the network side device based on the first setting information, but also by the terminal device based on the first setting information. To this end, the network side device may transmit the first setting information to the terminal device, whereby the terminal device determines the time domain information corresponding to the sidelink configuration grant transmission resource, and determines the first hybrid automatic repeat request process number based on the time domain information corresponding to the sidelink configuration grant transmission resource.

As an option, the first setting information
(1) A periodicity of a sidelink configuration grant transmission resource;
(2) the total number of HARQ process numbers corresponding to the currently configured grants;
(3) an HARQ process number offset used to determine the first HARQ process number corresponding to the currently configured grant;
(4) a time slot corresponding to a time domain resource of the sidelink configuration grant transmission resource.

In one embodiment, the configuration information includes a timeslot offset indication and a periodicity parameter, and a sidelink configuration grant transmission resource is determined based on the timeslot offset indication and the periodicity parameter. The timeslot offset indication is used to determine time domain information of a first sidelink configuration grant transmission resource within one system frame number period (or directly within a frame number period). The timeslot offset indication is expressed as a number of timeslots, and the number of timeslots represents a number of physical timeslots or a number of logical timeslots. A logical timeslot is a timeslot in a resource pool associated with the sidelink configuration grant transmission resource or a candidate timeslot for a resource pool. The periodicity parameter is used to determine a period of the sidelink configuration grant transmission resource, and is expressed as a number of timeslots, and the number of timeslots represents a number of physical timeslots or a number of logical timeslots. A logical timeslot is a timeslot in a resource pool associated with the sidelink configuration grant transmission resource or a candidate timeslot for a resource pool.

Optionally, in step S92, determining the first hybrid automatic repeat request process number based on time domain information corresponding to the sidelink configuration grant transmission resource may include the following execution steps S920 and S922:

In step S920, a periodicity parameter is determined based on the first configuration information, and the periodicity parameter is a periodicity of the sidelink configuration grant transmission resource.

In step S922, a first hybrid automatic repeat request process number is determined based on the time domain information and periodicity parameters corresponding to the sidelink configuration grant transmission resource.

As an alternative, the period of the sidelink configuration grant transmission resource is expressed in terms of the number of time slots, which is used to describe the number of time slots in the resource pool in which the sidelink configuration grant transmission resource is located. Or, as an alternative, the period of the sidelink configuration grant transmission resource is expressed in terms of the number of time slots, which is used to describe the number of candidate time slots for the resource pool.

When the parameter periodicity is expressed as the number of time slots, the corresponding first HARQ process number is determined based on the time domain position of the sidelink configuration grant transmission resource in the resource pool in which the sidelink configuration grant is located, using the formula HARQ Process ID = [floor (CURRENT_slot / periodicity)] mod nrofHARQ-Processes + harq-procID-offset. The meaning of each parameter in the formula is as follows.

(1) CURRENT_slot represents a timeslot corresponding to the time domain resource of the sidelink configuration grant transmission resource, and the index of the timeslot is the timeslot index in the resource pool in which the sidelink configuration grant is located. The value range of this parameter is [0, N-1], where N represents the total number of timeslots contained in the current resource pool, and the index of the timeslot is the timeslot index in the resource pool in which the sidelink configuration grant is located.

(2) periodicity represents the period of the sidelink configuration grant transmission resource and is expressed in time slots. It also represents the number of time slots in the resource pool in which the sidelink configuration grant is located.

(3) nrofHARQ-Processes represents the total number of HARQ process numbers corresponding to the sidelink configuration grant.

(4) harq-procID-offset is used to determine the first HARQ process number corresponding to the sidelink configuration grant. Optionally, if the network side device does not configure this parameter, the value of this parameter is 0.

In the above formula, mod represents the modulo operation and floor represents the truncation operation.

As shown in FIG. 8 again, the network side device configures the transmission resources of the sidelink configuration grant in a resource pool. The three time slots of the period of the sidelink configuration grant represent the three time slots in the resource pool. The first time slot position of the sidelink configuration grant is time slot 2, and according to the period of the sidelink configuration grant, time slots such as time slot 5, time slot 8, time slot 11, etc. include the transmission resources of the sidelink configuration grant.

In the above formula for calculating the HARQ process number, CURRENT_slot represents the time slot in which the transmission resource of the sidelink configuration grant is located in the resource pool, i.e., time slot 2, time slot 5, time slot 8, time slot 11, time slot 14, time slot 17...time slot 3032, etc. Periodicity represents the period of the transmission resource of the sidelink configuration grant, which can be expressed as the number of time slots in the resource pool in which the sidelink configuration grant is located, i.e., the period is three time slots. If the parameters are set such that nrofHARQ-Processes = 4 and harq-procID-offset = 0, the HARQ process numbers corresponding to the sidelink configuration grant are 0, 1, 2, and 3, respectively. In this embodiment, the HARQ process numbers corresponding to the transmission resources in the time domain positions of the sidelink configuration grant, such as time slot 2, time slot 5, time slot 8, time slot 11, time slot 14, and time slot 17, are 0, 1, 2, 3, 0, 1, etc., respectively.

In the process of determining the first hybrid automatic repeat request process number based on the time domain information corresponding to the sidelink configuration grant transmission resource, the network side device configures the sidelink configuration grant transmission resource in the terminal, and determines the corresponding first HARQ process number based on the time domain location of the sidelink configuration grant transmission resource in the sidelink according to the formula: HARQ Process ID = [floor (CURRENT_slot × 10 / (numberOfSlotsPerFrame × periodicity))] mod nrofHARQ-Processes + harq-procID-offset. The meaning of each parameter in the formula is as follows:

(1) numberOfSlotsPerFrame represents the number of time slots contained in each radio frame (Frame or Radio Frame).

(2) periodicity represents the period of the sidelink configuration grant transmission resource and is expressed in milliseconds (ms).

(3) nrofHARQ-Processes represents the total number of HARQ process numbers corresponding to the current sidelink configuration grant.

(4) harq-procID-offset is used to determine the first HARQ process number corresponding to the current sidelink configuration grant. In one alternative embodiment, if the network side device does not configure this parameter, the value of this parameter is 0.

CURRENT_slot represents the time slot corresponding to the time domain resource of the sidelink configuration grant transmission resource, the value range of this parameter is [0, N-1], N represents the total number of time slots contained in the current resource pool, and the index of this time slot is the time slot index in the resource pool in which the sidelink configuration grant is located.

In one possible embodiment, CURRENT_slot = [(DFN x numberOfSlotsPerFrame) + slot number in the frame]. The slot number in the frame represents the index of the sidelink configuration grant transmission resource in one radio frame, and its value range is [0,M-1], where M represents the total number of time slots contained in one radio frame. DFN represents the Direct Frame Number. numberOfSlotsPerFrame represents the number of time slots contained in each radio frame (Frame or Radio Frame) and is determined by the subcarrier spacing of the sidelink carrier in which the sidelink transmission is located, or is determined by the uplink subcarrier spacing.

In one possible embodiment, CURRENT_slot = [(SFN x numberOfSlotsPerFrame) + slot number in the frame]. The slot number in the frame represents the index of the sidelink configuration grant transmission resource in one radio frame, and its value range is [0, M-1], where M represents the total number of time slots contained in one radio frame. SFN represents the System Frame Number. numberOfSlotsPerFrame represents the number of time slots contained in each radio frame (Frame or Radio Frame) and is determined by the subcarrier spacing of the sidelink carrier in which the sidelink transmission is located, or is determined by the uplink subcarrier spacing.

In the above formula, mod represents the modulo operation and floor represents the truncation operation.

Optionally, in step S91, determining time domain information corresponding to the sidelink configuration grant transmission resources based on the first configuration information may include the following execution steps S910 and S912.

In step S910, based on the first configuration information, an uplink control channel transmitted from the terminal in the uplink transmission resource is received, the uplink transmission resource and the sidelink configuration grant transmission resource belong to the same sidelink configuration grant period, and the uplink control channel is used by the terminal to report sidelink feedback information.

In step S912, time domain information corresponding to the sidelink configuration grant transmission resource is determined based on the time domain information of the uplink transmission resource.

In the process of configuring the sidelink configuration grant, the network side device further configures an uplink transmission resource for transmitting the PUCCH. Therefore, in each period of the sidelink configuration grant, there is one corresponding PUCCH transmission resource. The terminal device transmits sidelink feedback information to the network side device through the PUCCH. After receiving the PUCCH transmitted from the terminal device in the uplink transmission resource, the network side device can determine the time domain position of the transmission resource of the sidelink configuration grant that belongs to the same period as the PUCCH based on the PUCCH, and can further determine the HARQ process number corresponding to the sidelink configuration grant transmission resource based on the above formula.

Optionally, the method may further include the following execution step S94:

In step S94, at least one of a first parameter and a second parameter is determined, where the first parameter is used to determine a time interval between the uplink transmission resource and the sidelink feedback channel transmission resource, and the second parameter is used to determine a time interval between the sidelink feedback channel transmission resource and the sidelink configuration grant transmission resource.

The time slot resource of the PUCCH is a time slot in an SFN period, and the time slot of the sidelink configuration grant transmission resource is a time slot in an SFN period (or a DFN period). The time domain information of the transmission resource of the sidelink configuration grant is determined based on the SFN index (or DFN index) and the time slot number in the radio frame. The transmission of the PUCCH uses the uplink transmission resource, and its time domain position is determined by the SFN and the time slot number in the radio frame. As an option, the start time slots of the SFN period and the DFN period, i.e., SFN#0 and DFN#0, are not aligned, and there is a time interval.

Figure 10 is a schematic diagram of a time interval between the SFN period and the DFN period according to one alternative embodiment of the present invention. As shown in Figure 10, the network side device configures the transmission resource and PUCCH resource of the sidelink configuration grant, where the period of the sidelink configuration grant is 10 ms and corresponds to four HARQ process numbers, which are 0, 1, 2, and 3, respectively. The subcarrier interval of the sidelink carrier and the uplink carrier is both 15 kHz, that is, each radio frame includes 10 time slots. If the transmission time of the PUCCH determined based on the configuration information is time T, time T corresponds to SFN#0, time slot 8 of the sidelink configuration grant transmission resource, but corresponds to DFN#58, time slot 6.

Optionally, the network side device can know the time interval between the sidelink transmission time and the uplink transmission time, because the network side device can receive the PUCCH at time T and determine the time domain position in the sidelink corresponding to the time domain position T of the PUCCH based on the time domain position T of the PUCCH.

The sidelink configuration grant transmission resource associated with the PUCCH is a sidelink configuration grant transmission resource that belongs to the same sidelink configuration grant cycle as the PUCCH. For sidelink data transmitted in the sidelink configuration grant transmission resource in the cycle, the corresponding sidelink feedback information is reported to the network side device by the associated PUCCH, i.e., the PUCCH in the cycle.

Therefore, the network side device needs to determine the time interval between the uplink transmission resource and the sidelink feedback channel transmission resource, and/or the time interval between the sidelink feedback channel transmission resource and the sidelink configuration grant transmission resource.

Optionally, in step S912, determining time domain information corresponding to the sidelink configuration grant transmission resources based on the time domain information of the uplink transmission resources may include the following execution step S9120:

In step S9120, time domain information corresponding to the sidelink configuration grant transmission resource is determined based on at least one of the first parameter and the second parameter and the time domain information of the uplink transmission resource.

In one alternative embodiment, the first configuration information is further used to configure at least one of the uplink transmission resources and the first parameter.

When the network side device receives the PUCCH at time T, it determines the time domain position corresponding to the PSFCH based on the time interval between the PUCCH and the physical sidelink feedback channel (abbreviated as PSFCH) transmission resource. Furthermore, the network side device may determine the time domain position of the transmission resource of the sidelink configuration grant in the period in which the PSFCH is located, and further determine the HARQ process number corresponding to the sidelink transmission resource corresponding to the PUCCH.

For example, the network side device configures a transmission resource of a sidelink configuration grant for a terminal in a resource pool, and configures a PUCCH transmission resource. The resource pool includes a PSFCH transmission resource, and the period of the PSFCH is two time slots, i.e., in the resource pool, one time slot for PSFCH transmission is included every two time slots, and the time interval between the configured PUCCH time domain resource and the PSFCH is three time slots. Therefore, when the network side device receives the PUCCH, it can determine the time slot position of the PSFCH corresponding to the PUCCH based on the time slot position of the PUCCH time domain resource. In one selectable example, the time slot position of the PSFCH is the time slot in which the last PSFCH is located in the sidelink configuration grant transmission resource period. Thus, the network side device can determine the time slot in which the sidelink configuration grant transmission resource is located in the period in which the PSFCH is located based on the time slot of the PSFCH, and can further determine the HARQ process number corresponding to the sidelink configuration grant transmission resource.

As a result, in the process of determining the HARQ process number based on the sidelink time domain position corresponding to the sidelink configuration grant transmission resource, the network side device can determine the HARQ process number of the sidelink transmission corresponding to the configured PUCCH transmission resource based on the time interval between the sidelink and uplink.

Optionally, the method may further include the following steps S95 and S96:

In step S95, second setting information is sent to the terminal, and the second setting information is used to configure the resource pool.

In step S96, the second parameter is determined based on the second setting information.

In addition to transmitting the first setting information to the terminal device, the network side device may also transmit second setting information for setting a resource pool to the terminal device, and may further determine a time interval between the sidelink feedback channel transmission resource and the sidelink configuration grant transmission resource based on the second setting information.

Optionally, the method may further include the following execution step S97:

In step S97, if the uplink control channel carries negative information, send downlink control information to the terminal, where the downlink control information is used to schedule sidelink transmission resources, and the downlink control information includes a first hybrid automatic repeat request process number, where the downlink control information is used to schedule the terminal to retransmit sidelink data corresponding to the first hybrid automatic repeat request process number in the sidelink transmission resources.

In the sidelink configuration grant transmission, the network side device may configure a PUCCH transmission resource for the terminal device. The terminal may report sidelink feedback information to the network side device in the PUCCH transmission resource. When the network side device receives the NACK feedback information reported by the terminal, it dynamically allocates a retransmission resource for the sidelink transmission by DCI, and indicates the first HARQ process number in the DCI, so that the terminal device can retransmit the first sidelink data in the sidelink transmission resource scheduled by the downlink control information. Thus, when the network side device allocates a retransmission resource to the terminal device in a dynamic scheduling manner by DCI, it includes the first HARQ process number in the DCI. Therefore, after receiving the DCI, the terminal device can determine the first HARQ process number corresponding to the retransmission resource scheduled by the DCI.

Of course, in the sidelink configuration grant transmission, the network side device does not need to configure the PUCCH transmission resource in the terminal device. In this case, the terminal does not need to report sidelink feedback information to the network side device, that is, does not need to perform retransmission based on network scheduling. If the transmitting terminal receives a NACK in the PSFCH from the receiving terminal, the transmitting terminal can perform retransmission. However, the sidelink transmission of the transmitting terminal usually uses the sidelink configuration grant transmission resource allocated by the network side device. In this case, the HARQ process number corresponding to the sidelink transmission is determined independently by the transmitting terminal, regardless of the time domain position of the sidelink configuration grant transmission resource.

This embodiment further provides another information processing method executed in the network side device. FIG. 11 is a flowchart of another information processing method according to one embodiment of the present invention. As shown in FIG. 11, the method includes the following steps S1100 to S1104.

In step S1100, first configuration information is determined, and the first configuration information is used to configure uplink transmission resources.

In step S1101, time domain information corresponding to the uplink transmission resources is determined based on the first setting information.

In step S1102, a first hybrid automatic repeat request process number is determined based on time domain information corresponding to the uplink transmission resource.

Unlike the information processing method shown in FIG. 9, the information processing method shown in FIG. 11 does not determine the HARQ ID based on the time domain position of the sidelink transmission resource, but determines the HARQ ID based on the time domain position of the uplink transmission resource.

Optionally, the method may further include the following steps S1103 and S1104:

In step S1103, a periodicity parameter is determined based on the first setting information, the first setting information is further used to set a sidelink configuration grant transmission resource, the sidelink configuration grant transmission resource is used to transmit sidelink data, and the periodicity parameter is used to determine the periodicity of the sidelink configuration grant transmission resource.

The sidelink configuration grant transmission resource is associated with the uplink transmission resource, i.e., for sidelink data transmitted in the sidelink configuration grant transmission resource, the corresponding sidelink feedback information is transmitted to the network side device in the uplink transmission resource.

In step S1104, a first hybrid automatic repeat request process number is determined based on the time domain information and periodicity parameters corresponding to the uplink transmission resources.

In the first configuration information, a sidelink configuration grant transmission resource may be configured, and an uplink transmission resource may be configured. The transmission resource of the sidelink configuration grant configured by the network side device to the terminal device is periodic, and each period includes a maximum of N_max (N_max=2 or 3) sidelink configuration grant transmission resources, and one PUCCH transmission resource is configured in each period. The terminal device transmits sidelink data using the sidelink configuration grant transmission resource in the period, and reports sidelink feedback information to the network side device using the PUCCH transmission resource. The network side device then determines whether a retransmission resource needs to be assigned to the terminal based on the sidelink feedback information.

Optionally, the time domain information corresponding to the sidelink configuration grant transmission resource is a time slot index of the sidelink configuration grant transmission resource in a resource pool. The periodicity parameter is expressed in terms of the number of time slots, which is the number of time slots in the resource pool or the number of candidate time slots for the resource pool.

One DFN period includes 10240 subframes, and the period of the synchronization signal is 160 ms. Assuming that one synchronization period includes two synchronization subframes, there are 128 synchronization subframes in one DFN period, and the length of the bitmap for indicating the time domain resources of the resource pool is 10 bits. Therefore, two reserved subframes are required, and the number of remaining subframes is (10240-128-2=10110), which is divisible by the 10 bits of the bitmap length, so that the remaining subframes are renumbered 0, 1, 2, ..., 10109, and the first 3 bits of the bitmap are 1 and the remaining 7 bits are 0. That is, in the remaining subframes, the first 3 subframes of each of the 10 subframes belong to the resource pool, and the remaining subframes do not belong to the resource pool. To indicate whether all subframes belong to the resource pool, the bitmap needs to be repeated 1011 times in the remaining subframes, and since there are three subframes in each bitmap period, a total of 3033 subframes belong to the resource pool in one DFN period. Each time slot index in the resource pool corresponds to one time slot index in the DFN period. For example, time slots 0, 1, 2, 3, 4, and 5 in the resource pool correspond to time slots 0, 2, 4, 13, 14, and 15 in the DFN period. When the network configures a sidelink configuration grant transmission resource, it is associated with one resource pool, and the sidelink configuration grant transmission resource configured by the network is a transmission resource located in the one resource pool.

In this embodiment, the time domain information corresponding to the sidelink configuration grant transmission resource is the time slot index of the sidelink configuration grant transmission resource in the resource pool. For example, in the above embodiment, the resource pool in which the sidelink configuration grant transmission resource is located includes 3033 subframes, so the time domain information corresponding to the sidelink configuration grant transmission resource is the time slot index in the resource pool, i.e., the time slot index in the range [0, 3032].

Optionally, the time domain information corresponding to the sidelink configuration grant transmission resource is a timeslot index in the timeslots used for the resource pool. For example, for the above embodiment, the timeslot set that can be used for the resource pool is the remaining subframes, and the corresponding timeslot index range is [0, 10109].

Optionally, the method may further include the following execution step S1105:

In step S1105, send downlink control information to the terminal, where the downlink control information is used to schedule sidelink transmission resources, and the downlink control information includes a first hybrid automatic repeat request process number.

In one alternative embodiment, the terminal transmits a negative response to the network side device in the uplink transmission resource. If the network side device detects a negative response in the uplink transmission resource, it transmits downlink control information to the terminal, and the downlink control information includes a first HARQ process number. After receiving the downlink control information, the terminal can obtain the first HARQ process number from the downlink control information.

In the sidelink configuration grant transmission, the network side device may configure a PUCCH transmission resource for the terminal device. The terminal may report sidelink feedback information to the network side device in the PUCCH transmission resource. When the network side device receives the NACK feedback information reported by the terminal, it dynamically allocates a retransmission resource for the sidelink transmission by DCI, and indicates the first HARQ process number in the DCI, so that the terminal device can retransmit the first sidelink data in the sidelink transmission resource scheduled by the downlink control information. Thus, when the network side device allocates a retransmission resource to the terminal device in a dynamic scheduling manner by DCI, it includes the first HARQ process number in the DCI. Therefore, after receiving the DCI, the terminal device can determine the first HARQ process number corresponding to the retransmission resource scheduled by the DCI.

For example, the network side device transmits first configuration information to the terminal, and the first configuration information is used to configure a sidelink configuration grant transmission resource and an uplink transmission resource. The terminal transmits sidelink data on the sidelink configuration grant transmission resource. If the sidelink feedback information received by the terminal is a NACK, the terminal transmits a NACK to the network side device on the uplink transmission resource. Then, the network side device determines a first HARQ process number based on a time domain position of the uplink transmission resource, and schedules a sidelink transmission resource for the terminal by the DCI for retransmission of sidelink data by the terminal, and includes the first HARQ process number in the DCI. The terminal receives the DCI, and can determine based on the first HARQ process number that the DCI is a retransmission scheduling for the NACK transmitted by the network side device on the uplink transmission resource. Furthermore, the terminal can determine that the DCI is a retransmission scheduling for the sidelink data transmitted on the sidelink configuration grant transmission resource associated with the uplink transmission resource. Therefore, the terminal retransmits the sidelink data in the sidelink transmission resources scheduled by the DCI.

Of course, in the sidelink configuration grant transmission, the network side device does not need to configure the PUCCH transmission resource in the terminal device. In this case, the terminal does not need to report sidelink feedback information to the network side device, that is, does not need to perform retransmission based on network scheduling. If the transmitting terminal receives a NACK in the PSFCH from the receiving terminal, the transmitting terminal can perform retransmission. However, the sidelink transmission of the transmitting terminal usually uses the sidelink configuration grant transmission resource allocated by the network side device. In this case, the HARQ process number corresponding to the sidelink transmission is determined independently by the transmitting terminal, regardless of the time domain position of the sidelink configuration grant transmission resource.

This embodiment further provides another information processing method executed in the network side device. FIG. 12 is a flowchart of another information processing method according to one embodiment of the present invention. As shown in FIG. 12, the method includes the following steps S1200 to S1202.

In step S1200, configuration information is received from the network side device, and the configuration information is used for uplink transmission resources.

In step S1201, time domain information corresponding to the uplink transmission resources is determined based on the configuration information.

In step S1202, a first hybrid automatic repeat request process number is determined based on time domain information corresponding to the uplink transmission resource.

Unlike the information processing method shown in FIG. 7, the information processing method shown in FIG. 12 does not determine the HARQ ID based on the time domain position of the sidelink transmission resource, but determines the HARQ ID based on the time domain position of the uplink transmission resource.

Optionally, the configuration information is further used to configure sidelink configuration grant transmission resources, which are used to transmit sidelink data.

In the above configuration information, a sidelink configuration grant transmission resource may be configured, and a PUCCH transmission resource may be configured. The PUCCH transmission resource is a PUCCH resource corresponding to the sidelink configuration grant transmission resource, that is, the sidelink feedback information associated with the sidelink data transmitted in the sidelink configuration grant transmission resource is reported to the network side device by the PUCCH transmission resource. For the terminal device, the first hybrid automatic repeat request process number can be determined based on the time domain position of the uplink transmission resource.

Optionally, the method may further include the following execution steps S1203 to S1205.

In step S1203, at least one of a first parameter and a second parameter is determined, where the first parameter is used to determine a time interval between an uplink transmission resource and a sidelink feedback channel transmission resource, and the second parameter is used to determine a time interval between a sidelink feedback channel transmission resource and a sidelink configuration grant transmission resource.

The time slot resource of the PUCCH is a time slot in an SFN period, and the time slot of the sidelink configuration grant transmission resource is a time slot in an SFN period (or a DFN period). The time domain information of the transmission resource of the sidelink configuration grant is determined based on the SFN index (or DFN index) and the time slot number of the sidelink configuration grant transmission resource in the radio frame. The transmission of the PUCCH uses an uplink transmission resource, and its time domain position is determined by the SFN and the time slot number in the radio frame. Optionally, the start time slots of the SFN period and the DFN period, i.e., SFN#0 and DFN#0, are not aligned, and there is a time interval.

The sidelink configuration grant transmission resource associated with the PUCCH is a sidelink configuration grant transmission resource that belongs to the same sidelink configuration grant cycle as the PUCCH. For sidelink data transmitted in the sidelink configuration grant transmission resource in the cycle, the corresponding sidelink feedback information is reported to the network side device by the associated PUCCH, i.e., the PUCCH in the cycle.

Therefore, the network side device needs to determine the time interval between the uplink transmission resource and the sidelink feedback channel transmission resource, and/or the time interval between the sidelink feedback channel transmission resource and the sidelink configuration grant transmission resource.

Optionally, the method may further include the following steps S1204 and S1205:

In step S1204, based on at least one of the first parameter and the second parameter and the time domain information corresponding to the uplink transmission resource, time domain information corresponding to the sidelink configuration grant transmission resource is determined, and a correspondence relationship between the uplink transmission resource and the sidelink configuration grant transmission resource is obtained.

In step S1205, a sidelink configuration grant transmission resource corresponding to the first hybrid automatic repeat request process number is determined based on the first hybrid automatic repeat request process number and the correspondence between the uplink transmission resource and the sidelink configuration grant transmission resource.

When the network side device receives the PUCCH at time T, it determines a first hybrid automatic repeat request process number based on the time domain resource of the PUCCH, and further determines a time domain position corresponding to the PSFCH based on the time interval between the PUCCH and the physical sidelink feedback channel (abbreviated as PSFCH) transmission resource. Furthermore, the network side device determines a time domain position of the transmission resource of the sidelink configuration grant in the period in which the PSFCH is located, and further determines the transmission resource of the sidelink configuration grant corresponding to the first HARQ process number.

For example, the network side device configures a transmission resource of a sidelink configuration grant for a terminal in a resource pool, and configures a PUCCH transmission resource. The resource pool includes a PSFCH transmission resource, and the period of the PSFCH is two time slots, i.e., in the resource pool, one time slot for PSFCH transmission is included every two time slots, and the time interval between the configured PUCCH time domain resource and the PSFCH is three time slots. Therefore, when the network side device receives the PUCCH, it can determine the first HARQ process number based on the time slot position of the PUCCH time domain resource. Then, the network side device determines the time slot position of the PSFCH corresponding to the PUCCH based on the time interval between the PUCCH transmission resource and the PSFCH transmission resource. In one selectable example, the time slot position of the PSFCH is the time slot in which the last PSFCH is located in the sidelink configuration grant transmission resource period. As a result, the network side device can determine the time slot in which the sidelink configuration grant transmission resource is located in the period in which the PSFCH is located based on the time slot of the PSFCH, and can further determine that the sidelink configuration grant transmission resource corresponds to the first HARQ process number.

As a result, in the process of determining the HARQ process number based on the time domain position of the PUCCH transmission resource, the network side device can determine the HARQ process number corresponding to the configured sidelink configuration grant transmission resource based on the time interval between the sidelink and uplink.

Optionally, the method may further include the following execution steps S1206 to S1208.

In step S1206, first sidelink data is transmitted in the sidelink configuration grant transmission resource, and the first sidelink data corresponds to a first hybrid automatic repeat request process number.

The terminal device may transmit first sidelink data using a first HARQ process number. The first sidelink data may include a PSCCH and a PSSCH. The terminal device may further include the first HARQ process number in the SCI, i.e., the sidelink data transmitted in the PSSCH corresponds to the first HARQ process number.

Optionally, the method may further include the following steps S1207 and S1208:

In step S1207, downlink control information sent from a network side device is received, the downlink control information is used to schedule sidelink transmission resources, and the downlink control information includes a first hybrid automatic repeat request process number.

In step S1208, the first sidelink data is retransmitted in the sidelink transmission resource.

In transmitting the sidelink configuration grant, the network side device may configure a PUCCH transmission resource for the terminal device. The terminal may report sidelink feedback information to the network side device in the PUCCH transmission resource.

Optionally, the network side device configures one PUCCH transmission resource in each sidelink configuration grant period. In one sidelink configuration grant period, the terminal transmits the first sidelink data to the receiving terminal through the sidelink configuration grant transmission resource, corresponding to the first HARQ process number. If the sidelink feedback information received by the terminal is a NACK, the terminal reports a NACK to the network through the PUCCH in the period. When the network side device receives the NACK feedback information reported by the terminal, it determines a first HARQ process number based on the time domain position of the PUCCH transmission resource, dynamically allocates a retransmission resource for the sidelink transmission through DCI, and indicates the first HARQ process number in DCI, so that the terminal device can retransmit the first sidelink data in the sidelink transmission resource scheduled by the downlink control information.

Optionally, the method may further include the following execution step S1209:

In step S1209, second sidelink data is transmitted in the sidelink configuration grant transmission resource, and the second sidelink data corresponds to a second hybrid automatic repeat request process number.

When the terminal transmits sidelink data using a sidelink configuration grant transmission resource, the terminal determines a first HARQ process number based on time domain information of the sidelink configuration grant transmission resource. Furthermore, the terminal may pre-determine a mapping relationship between the first HARQ process number and the second HARQ process number. The terminal device may transmit second sidelink data in the sidelink configuration grant transmission resource using the second HARQ process number based on the mapping relationship. The second sidelink data may include PSCCH and PSSCH. In addition, the terminal device may further include the second HARQ process number in the SCI, i.e., the sidelink data transmitted in the PSSCH corresponds to the second HARQ process number.

Optionally, the method may further include the following execution steps S1210 to S1212.

In step S1210, a mapping relationship between the first hybrid automatic repeat request process number and the second hybrid automatic repeat request process number is determined.

Optionally, the method may further include the following steps S1211 and S1212:

In step S1211, downlink control information sent from a network side device is received, the downlink control information is used to schedule sidelink transmission resources, and the downlink control information includes a first hybrid automatic repeat request process number.

In step S1212, the second sidelink data is retransmitted in the sidelink transmission resource based on the mapping relationship between the first hybrid automatic repeat request process number and the second hybrid automatic repeat request process number.

The network side device determines the first HARQ process number according to the PUCCH transmission resource, and determines that the process number corresponding to the transmission resource of the sidelink configuration grant is the first HARQ process number based on the correspondence relationship between the PUCCH and the sidelink configuration grant transmission resource. If the network side device receives a NACK, it dynamically allocates a retransmission resource to the sidelink transmission by DCI, and indicates the first HARQ process number in the DCI. After receiving the DCI and obtaining the first HARQ process number from the DCI, the terminal device may determine that the retransmission resource is a retransmission schedule for the sidelink transmission of the second HARQ process number based on the mapping relationship between the first HARQ process number and the second HARQ process number.

As can be seen, the first HARQ process number determined by the terminal device based on the time domain information of the sidelink configuration grant transmission resource may be different from the second HARQ process number used when transmitting data on the sidelink configuration grant transmission resource, and the terminal device can further determine the mapping relationship between the first HARQ process number and the second HARQ process number. Thus, the terminal device can more flexibly or autonomously determine the HARQ process number for sidelink transmission.

This embodiment further provides another information processing method executed on the terminal device.

The first hybrid automatic repeat request process number is determined by the formula: HARQ Process ID = [floor (CURRENT_slot / periodicity)] mod nrofHARQ-Processes + harq-procID-offset. The meaning of each parameter in the formula is as follows:

(1) CURRENT_slot represents the time slot index of the sidelink configuration grant transmission resource. Furthermore, the parameter represents the time slot index within one radio frame period. The value range of the parameter is [0, N-1]. N represents the total number of time slots included in one radio frame period. For example, in the case of 15 kHz subcarrier spacing, 10 time slots are included in one radio frame, and 10240 time slots are included in one radio frame period, so the value range of the parameter is [0, 10239].

(2) periodicity represents the period of the sidelink configuration grant transmission resource. Alternatively, the parameter is expressed as a time length, e.g., 100 ms, 200 ms, 500 ms, etc. Alternatively, the parameter is expressed as the number of time slots. Furthermore, the parameter is expressed as the number of physical time slots. For example, periodicity=100 time slots, 200 time slots, etc. In the case of 15 kHz subcarrier spacing, a period of 100 ms can correspond to 100 time slots. In the case of 30 kHz subcarrier spacing, a period of 100 ms can correspond to 200 time slots. By analogy therewith.

(3) nrofHARQ-Processes represents the total number of HARQ process numbers corresponding to the sidelink configuration grant.

(4) harq-procID-offset is used to determine the first HARQ process number corresponding to the sidelink configuration grant. Optionally, if the network side device does not configure this parameter, the value of this parameter is 0.

In the above formula, mod represents the modulo operation and floor represents the truncation operation.

In one alternative embodiment, the terminal receives configuration information from a network side device and determines a time slot in which a sidelink configuration grant transmission resource is located based on the configuration information.

As an option, depending on the above setting information,
(1) A periodicity of a sidelink configuration grant transmission resource;
(2) the total number of HARQ process numbers corresponding to the currently configured grants;
(3) an HARQ process number offset used to determine the first HARQ process number corresponding to the currently configured grant;
(4) a time slot corresponding to a time domain resource of the sidelink configuration grant transmission resource.

In one alternative embodiment, the configuration information includes a time slot offset indication, a time domain resource indication, and a periodicity parameter. Based on the time slot offset indication, the time domain resource indication, and the periodicity parameter, a sidelink configuration grant transmission resource is determined. The time slot offset indication is used to determine the time domain information of the first sidelink configuration grant transmission resource in one system frame number period (or directly in the frame number period). Optionally, the time slot offset indication is expressed by the number of physical time slots. The time domain resource indication is used to determine the time domain location of the sidelink configuration grant transmission resource configured in one sidelink configuration grant period. For example, based on the time domain resource indication, one, two, or three values are determined, which are the time slot intervals of the time domain location of the sidelink configuration grant transmission resource with respect to the time domain location determined based on the time slot offset indication. For example, if the two values determined based on the time domain resource indication information are 3 and 7, respectively, and the time domain position determined based on the time slot offset indication information is time slot 1, the time slots in which the sidelink configuration grant transmission resource is located are time slots 4 and 8. The periodicity parameter is used to determine the periodicity of the sidelink configuration grant transmission resource, and is expressed as a time length or a number of physical time slots.

For example, the terminal receives configuration information for configuring sidelink configuration grant transmission resources transmitted from the network, and the time slots in which the transmission resources of the sidelink configuration grant are located based on the configuration information are 2, 102, 202, 302, 402, 502, 602, 702, 802, etc., the period of the sidelink configuration grant is 100 time slots, includes 3 HARQ process numbers, and the HARQ process number offset is 0. Therefore, the HARQ process numbers corresponding to the sidelink configuration grant are 0, 1, and 2. Thus, the HARQ process numbers corresponding to the transmission resources of each sidelink configuration grant are determined according to the above formula. Table 1 shows the correspondence relationship between the sidelink configuration grant transmission resources and the HARQ process numbers, and Table 1 is as follows.

Optionally, the method further comprises:
The method may further include the step of: the terminal transmitting first sidelink data on the sidelink configuration grant transmission resources , the first sidelink data corresponding to a second hybrid automatic repeat request process number.

As an option, the second hybrid automatic repeat request process number is the same as the first hybrid automatic repeat request process number.

As an option, the second hybrid automatic repeat request process number is different from the first hybrid automatic repeat request process number, and the terminal device determines the correspondence between the first HARQ process number and the second HARQ process number.

The HARQ process number corresponding to the sidelink configuration grant transmission resource determined by the terminal device according to the above method is the first HARQ process number. The terminal device may transmit the first sidelink data using the second HARQ process number. The terminal determines the correspondence between the first HARQ process number and the second HARQ process number. The first sidelink data may include PSCCH and PSSCH. In addition, the terminal device may further include the second HARQ process number in the sidelink control information (SCI), i.e., the sidelink data transmitted in the PSSCH corresponds to the second HARQ process number.

Optionally, the network side device configures one PUCCH transmission resource in each sidelink configuration grant period. In one sidelink configuration grant period, the terminal transmits the first sidelink data to the receiving terminal through the sidelink configuration grant transmission resource. If the sidelink feedback information received by the receiving terminal is a NACK, the terminal reports a NACK to the network side device through the PUCCH in the period. The network side device can determine the time domain location of the corresponding sidelink configuration grant transmission resource based on the transmission resource of the PUCCH, and can thereby determine the HARQ process number corresponding to the sidelink data transmitted in the sidelink configuration grant transmission resource, i.e., the first HARQ process number. When the network side device receives the NACK feedback information reported by the terminal, it dynamically allocates a retransmission resource for the sidelink transmission through the DCI, and indicates the first HARQ process number in the DCI, so that the terminal device can retransmit the first sidelink data in the sidelink transmission resource scheduled in the downlink control information.

Optionally, the method may further include the following first to third execution steps:

In the first step, the terminal receives a DCI from a network side device, the DCI is used to schedule sidelink transmission resources, and the downlink control information includes a first HARQ process number.

In a second step, the terminal determines that the DCI is used to schedule the first sidelink data based on the first HARQ process number included in the DCI and the correspondence between the first HARQ process number and the second HARQ process number.

In a third step, the terminal retransmits the first sidelink data in the sidelink transmission resources scheduled in the DCI.

In one alternative embodiment, the network side device determines the first HARQ process number by adopting the following first to fourth steps.

In the first step, the network side device determines that it has received sidelink feedback information reported by the terminal on the PUCCH transmission resource.

In a second step, the network side device determines at least one of the first parameter and the second parameter. The first parameter is used to determine a time interval between the uplink transmission resource and the sidelink feedback channel transmission resource, and the second parameter is used to determine a time interval between the sidelink feedback channel transmission resource and the sidelink configuration grant transmission resource.

In a third step, the network side device determines a PUCCH transmission resource and a time slot of a corresponding sidelink transmission resource based on at least one of the first parameter and the second parameter.

In the fourth step, the network side device determines the first HARQ process number corresponding to the sidelink transmission resource by the formula: HARQ Process ID = [floor (CURRENT_slot / periodicity)] mod nrofHARQ-Processes + harq-procID-offset. The meaning of each parameter in the formula is as follows:

(1) CURRENT_slot represents the time slot index of the sidelink configuration grant transmission resource. Furthermore, the parameter represents the time slot index within one radio frame period. The value range of the parameter is [0, N-1]. N represents the total number of time slots included in one radio frame period. For example, in the case of 15 kHz subcarrier spacing, 10 time slots are included in one radio frame, and 10240 time slots are included in one radio frame period, so the value range of the parameter is [0, 10239].

(2) periodicity represents the period of the sidelink configuration grant transmission resource. Alternatively, the parameter is expressed as a time length, e.g., 100 ms, 200 ms, 500 ms, etc. Alternatively, the parameter is expressed as the number of time slots. Furthermore, the parameter is expressed as the number of physical time slots. For example, periodicity=100 time slots, 200 time slots, etc. In the case of 15 kHz subcarrier spacing, a period of 100 ms can correspond to 100 time slots. In the case of 30 kHz subcarrier spacing, a period of 100 ms can correspond to 200 time slots. By analogy therewith.

(3) nrofHARQ-Processes represents the total number of HARQ process numbers corresponding to the sidelink configuration grant.

(4) harq-procID-offset is used to determine the first HARQ process number corresponding to the sidelink configuration grant. Optionally, if the network side device does not configure this parameter, the value of this parameter is 0.

In the above formula, mod represents the modulo operation and floor represents the truncation operation.

13 is a schematic diagram of a terminal device independently determining a HARQ process number according to one alternative embodiment of the present invention. As shown in FIG. 13, the network side device configures a sidelink configuration grant transmission resource, and each period includes two sidelink configuration grant transmission resources, and the total number of HARQ processes of the sidelink configuration grant is 4, which are HARQ ID0, HARQ ID1, HARQ ID2, and HARQ ID3, respectively. As an option, the TX UE uses PSSCH1, PSSCH2, PSSCH3, and PSSCH4 to perform initial transmission of HARQ ID0, HARQ ID1, HARQ ID2, and HARQ ID3, respectively. If all of the feedback information received by the TX UE is NACK, it may continue to use PSSCH5, PSSCH6, PSSCH7, and PSSCH8 to retransmit HARQ ID0, HARQ ID1, HARQ ID2, and HARQ ID3, respectively.

As an option, the TX UE uses PSSCH1 and PSSCH2 for initial transmission and retransmission of HARQ ID 0, respectively. The TX UE uses PSSCH3 and PSSCH4 for initial transmission and retransmission of HARQ ID 1, respectively. The TX UE uses PSSCH5 and PSSCH6 for initial transmission and retransmission of HARQ ID 2, respectively. The TX UE uses PSSCH7 and PSSCH8 for initial transmission and retransmission of HARQ ID 3, respectively.

As an option, the TX UE uses PSSCH1 and PSSCH2 for the initial transmission and retransmission of HARQ ID 0, respectively. If the received feedback information is still NACK, it continues to use PSSCH3 to retransmit HARQ ID 0. If the received feedback information becomes ACK, it uses PSSCH4 for the initial transmission of HARQ ID 1, or uses PSSCH4 for the initial transmission of HARQ ID 0, in which case different transmission blocks correspond to the sidelink data transmitted by PSSCH4 and PSSCH1.
